UNITED STATES FURNACE WALL CONSTRUCTION PhilipWashington Antill, Ridgefield Park, N. J., assignor to American Arch Company, New York, N. Y., a corporation of Delaware Application December 6, 1926. Serial No. 152,768

Renewed July 23, 1930 42 Claims.

This invention relates to furnace wall construction, and particularly to unit or sectional walls. One of the primary objects of the invention is the improvement of hollow furnace walls of the sectional type.

Another'object of the invention is to provide such a wall of less difiiculty of construction and repair, and, at the same time, greater stability and strength than those now commonly in use.

A'further object is the provision of a wall construction of the character specified wherein the inner refractory portion shall be relieved of great stresses resulting from temperature variations or other causes.

Still another object is the direct utilization or the primary strength members of the outer or supporting wall portion in the supporting structure for the inner wall.

How the foregoing, together with such other 2119 advantages as are incident to my invention, or

mayoccur to those skilled in the art, are obtained, will beclear from the following description of a preferred embodiment of the invention viewed in the light of the accompanying drawings thereof, wherein- Fig. 1 is an elevation of a portion of a wall section constructed in accordance with the present invention. m Fig. 2 is a plan view taken on the line 22 of Fig. l, with the three upper rows of bricks removed; and v Fig. 3 is an enlarged view taken on the line 3-3 of Fig. 2, with certain parts broken away.

Referring, first, toFig. 3, it will be seen that l have therein illustrated part of a hollow furnace wall having a solid or fixed outer portion 2, which may-be of any suitable construction, and an inner refractory portion 3 supported therefrom, with an air space 4 between the two.

The inner-wall 3 is built up of a vertical series of horizontally disposed units or sections, each oi which is supported by a row of supporting castlugs or hanger members 5 (see Figs. 1 to 3). These hangers each have, at the head, a groove or slot 6, preferably re-enforced by laterally extending flanges 7, for direct engagement with the structural work oi the outer wall 2, such structural work being here shown as comprising horizontally disposed strength members or iibeams 2,'although it will be understood that other forms of beams or like members may be used in the construction of the outer wall. Each hanger 5 has a pair of lateral flanges forming a .cross-' web 16, and carries at the bottom a foot 9, which together with the base of the main web 10 of the hanger and the lateral bracket-like portions 11, forms a pair of pockets or recesses 12 adapted to support the lowermost bricks 13 of each wall section. The lower end of the hanger is adapted to bear at 14 against a shoulder 15 on the subjacent hanger.

Each wall section is built up on the supporting bricks or blocks 13, and comprises, in addition to said blocks, alternate rows or courses of tied and filler blocks 18, 18 and intermediate blocks 17, respectively. That is, each course of intermediate blocks 17 lies between adjacent courses of tied and filler blocks 18, 18*, the tied or secured blocks 18 being tied or supported laterally by the hangers 5 in a 'manner to be described. At the top of each wall section there is provided a row of L-shaped blocks 19 adapted to make a vertically sliding joint at 20 with the block 13 of the superjacent wall section, smaller blocks 21 and a sand or other seal 22 being provided in the gap between the L-blocks 19 and the blocks 18, 18 next above, as shown in Fig. 3.

By reference particularly to Figs. 2 and 3, it will be seen that the tied or secured blocks 18 are 86 secured as against lateral displacement by the tie members 23, 24, each of which has a pair of depending lugs 25 engaging sockets or vertical holes 26 in the cars 27 of the said bricks 18. The tie members or bars 23, which are alternated vertical- 8 ly with the ties 24, are of such a length as to engage the lateral webs l6 of adjacent hangers 5, and the shorter tie bars 2% are kept in their proper position and supported as against lateral displacement by the vertical rods 28, each of which extends through one vertical series or the alternating tie members 23, 24;, and rests at the bottom upon one of the blocksl3. The tied or secured bricks 18 are recessed or shouldered at their rear outside edges, as shown at 29 in Fig. 2, while the filler blocks 18 each have a similarly positioned boss or overhung edge portion 30 adapted to engage the shoulder of the adjacent secured brick, so that each pair of bricks 18 are securely held by ship-lap joints with the ad- Mm jacent brick 18 on either side.

Briefly reviewing the foregoing; it will be clear that each section of the refractory wall is built upon the brick 13 supported by the hangers 5, each row of brick 17 thereabove lying between rows of secured brick 18. and filler brick l8 arranged in pairs horizontally, vertically alternating pairs of the brick 18 being tied to the hangers 5, the other bricks 18 being merely tied together in pairs, with vertical rods 28 tying together the no care of expansion and contraction due totemperature changes, while, at the same time, main=- taining proper lateral support and a solid foundation for the weight of each section, and permitting easy,renewal of whole wall sections or parts thereof, or of the individual bricks or tie members therein. It has also the advantages of hollow wall construction, ViZ., the provision for circulating air therein,'the preheating thereby of air for combustion, and the cooling and protection of the brickwork and the metallic mem bers.

The metallic supporting and retaining struc-= ture, and particularly the hanger members and tie bars, considered per se, including various detailed features of their form and construction,

' are fully described and claimed in my copending divisional application, Serial No. 680,716, filed July 17th, 1933.
